The compound shown here is used to treat trypanosome infection. What amino acid does the compound resemble?
A decapeptide which could resist burns was isolated from an endemic plant from Mt. Mayon. Deduce the amino acid sequence of the decapeptide given the following informations.
Mercaptoethanol gave two pentapeptides F1 and F2.
Chymotrypsin treatment of F1 releases S and a tetrapeptide (C,K,F,M) while F2 gave a dipeptide (M,S) and a tripeptide (C,F,K)
F1 when treated with CNBr released a free homoserine lactone and a tetrapeptide.
Trypsin treatment of F1 gave a tripeptide and a dipeptide.
F2 treated with carboxypeptidase released free M while with trypsin gave free K and a tetrapeptide.
How does the structure of chymotrypsin enable it to cleave only peptide
bonds that are adjacent to aromatic R groups? Suppose a protease could only
cleave adjacent to Lysine and Arginine; how would the structure of this protein
differ from that of chymotrypsin?

- You have isolated from a rare fungus an octapeptide that prevents baldness and you wish to determine its amino acid sequence. The amino acid composition is K2, D, Y, F, G, S, A. Reaction of the intact peptide with dansyl chloride yields dansyl-A. Cleavage with trypsin yields peptides whose compositions are: (K, A, S) and (G, F, K) plus a dipeptide. Reaction with chymotrypsin releases free D, a tetrapeptide with composition (k, S, F, A) and a tripeptide whose composition following acid hydrolysis is (G, K, Y).
